In my circle of friends or Instagram and other social networking platforms often appear blurred picture, the nose is too close to the mouth of the case, the fact that the culprit is the loss of pixels, which is a normal phenomenon.
In fact, when we upload photos to social networking platforms, more or less pixels and the quality of the photos will be lost. The cause of this problem is largely attributable to these platforms in order to save capacity and traffic, it will automatically compress the photos.
Recently an artist to make a test, try to constantly repeated photo upload and download, to see whether there will be little effect on the picture quality, the result is terrible.
In fact, about 30 times to repeat the portrait has begun to lose their color, and gradually began to blur, and finally almost only a silhouette, even contours are invisible. Because we often only upload one photo, so this is essentially imperceptible compression.
